Background: The aim of this study was to establish whether pulmonary lobectomy using video-assisted thoracic surgery (VATS) can be safely performed by trainees with limited experience with open lobectomy. Methods: Data were retrospectively collected from 251 patients who underwent VATS lobectomy at a single institution between October 2007 and April 2011. The surgical outcomes of the procedures that were performed by three trainee surgeons were compared to the outcomes of procedures performed by a surgeon who had performed more than 150 VATS lobectomies. The cumulative failure graph of each trainee was used for quality assessment and learning curve analysis. Results: The surgery time, estimated blood loss, final pathologic stage, thoracotomy conversion rate, chest tube duration, duration of hospital stay, complication rate, and mortality rate were comparable between the expert surgeon and each trainee. Cumulative failure graphs showed that the performance of each trainee was acceptable and that all trainees reached proficiency in performing VATS lobectomy after 40 cases. Conclusion: This study shows that trainees with limited experience with open lobectomy can safely learn to perform VATS lobectomy for the treatment of lung cancer under expert supervision without compromising outcomes.

The purpose of this study is to examine how much the service quality of the radiology department at the hospital is influential to customers' satisfaction and intents of reusing the department and informing it to others. For the purpose, this researcher surveyed 201 patients whon used the radiology department at the hospital. Findings of the study can be summarized as follows. First, the surveyed patients' perceptions of the service quality of the radiology department in accordance with their demographic characteristics were investigated to find that among the subjects, women were perceiving the radiological technician as more kind than men were. Among the subjects, women were higher in customer satisfaction about the service quality of the radiology department and intents of reusing the department and informing it to others than men were. Second, out of factors of the radiology department's service quality, those who were significantly affecting customer satisfaction included waiting time for treatment at the department, kindness of the radiological technician, environment of the radiography room and facilities of the department. Third, customer satisfaction was significantly affecting the intent of reuse. Fourth, customer satisfaction was significantly influencing the intent of informing to others. In other words, the more customers are satisfied with the service quality of the radiology department, the more they are likely to inform the department to others and reuse it. In conclusion, the sustainable growth and effective management of the medical institution requires improving the service quality of its department of radiology and thereon maximizing customer satisfaction.

Background: Esophageal surgery in esophageal cancer has low curative resection rate and its resut has not improved even after the extended lymphnode dissection. To evaluate the effectiveness of cervical lymph node dissection, we compare the node of cervical lymph node metastasis in patients esophageal cancer. Materials and methods: We studied a series of 32 patients who underwent operation for thoracic esophageal carcinoma at our institution. The 25 patient who underwent curative surgery were divided into two groups. Both groups A and B underwent transthoracic esophagectomies with mediastinal and abdominal lymphadenectomies only, but group B also underwent bilateral lower neck node dissection. Results: The rate of operative complications did not differ significantly between two groups. No operative and hospital mortalities were noted in either group. However, the mean anesthetic time was significantly longer in group B(mean: 90 minutes). Neck node metastasis was revealed in 27% of group B. Conclusions: Therfore, neck node dissection is meaningful for surgical treatment of the thoracic esophageal carcinoma. The longterm survival rate should be compared later.

Objective : The objective of study is to evaluate the incidence of leptomeningeal carcinomatosis (LMC) in breast cancer patients with parenchymal brain metastases (PBM) and clinical risk factors for the development of LMC. Methods : We retrospectively analyzed 27 patients who had undergone surgical resection (SR) and 156 patients with whole brain radiation therapy (WBRT) as an initial treatment for their PBM from breast cancer in our institution and compared the difference of incidence of LMC according to clinical factors. The diagnosis of LMC was made by cerebrospinal fluid cytology and/or magnetic resonance imaging. Results : A total of 27 patients (14%) in the study population developed LMC at a median of 6.0 months (range, 1.0-50). Ten of 27 patients (37%) developed LMC after SR, whereas 17 of 156 (11%) patients who received WBRT were diagnosed with LMC after the index procedure. The incidence of LMC was significantly higher in the SR group compared with the WBRT group and the hazard ratio was 2.95 (95% confidence interval; 1.33-6.54, p<0.01). Three additional factors were identified in the multivariable analysis : the younger age group (<40 years old), the progressing systemic disease showed significantly increased incidence of LMC, whereas the adjuvant chemotherapy reduce the incidence. Conclusion : There is an increased risk of LMC after SR for PBM from breast cancer compared with WBRT. The young age (<40) and systemic burden of cancer in terms of progressing systemic disease without adjuvant chemotherapy could be additional risk factors for the development of LMC.

Objective : The objective of this study is to verify the characteristics of acupuncture methods of Joseon Dynasty by looking into the relationship between five viscera diagnosis and acupuncture methods. Material & Method : In the process, I've reviewed the relationship between meridian/exterior and viscera/bowels, along with a thorough comparison of the academic tendency in acupuncture of Ming-China, Qing-China and Joseon. Result & Conclusion : The two fields of meridian and exterior, and viscera and bowels had been theoretically merged, and based upon that, foundation methods applying the five viscera diagnosis were designed. Joseon acupuncture exceeded the existing concept of viscera which simply related itself to the exterior meridian and exterior by integrating the concepts from the visceral manifestation theory. With this, large proportions of medicine related to the visceral manifestation theory were invited into acupuncture, expanding therapeutic boundaries for acupuncture treatment. A historical review on medical texts starts from the Hyangyakjipseongbang("鄕藥集成方") which familiarized the public with mainstream acupuncture knowledge up until the Song dynasty, followed by Uibangyuchwi("醫方類聚"), which sparked up interest on the acupuncture methods based on viscera and bowels. Donguibogam("東醫寶鑑") organized the medical theories up until then, building a foundation upon which viscera/bowel-based acupuncture was able to develop further. In Chimgugyeongheombang("鍼灸經驗方"), viscera/bowel-based acupuncture methods started to blossom, integrating the meridian and exterior theory with the viscera manifestation theory, which in turn provided various methods through five viscera diagnosis. In the Saamdoin acupuncture method(舍岩道人鍼法), diagnostic criteria moved on to the five viscera diagnosis, and new methods resulting from the inter-complimentary and inter-prohibiting relationships between the five phases were introduced, opening a new world of acupuncture.

Purpose: Attention deficit hyperactivity disorder (ADHD) is a common disorder in school-aged children. Patients with restless legs syndrome (RLS) often present with ADHD symptoms and vice versa. This study was the first to attempt to identify the prevalence of RLS and sleep problems in children with ADHD in Korea. Methods: Patients diagnosed with ADHD were asked to complete a sleep questionnaire. The sleep questionnaire included items to help identify the presence of four typical symptoms that are used as diagnostic criteria for RLS. Results: A total of 56 patients, including 51 boys and 5 girls (mean age, 10.7 years old) participated. Of these, 24 complained of pain, discomfort, or an unpleasant sensation in the legs. Based on the RLS diagnostic criteria, 2 patients were diagnosed with definite RLS and 4 with probable RLS. There were no significant differences in age, medication dosage, or neuropsychological test scores between the patients with and without RLS symptoms. Conclusion: Approximately 42.9% of patients with ADHD presented with RLS symptoms and 7.1% of these were diagnosed with RLS. Patients with ADHD also experienced various other sleep disorders. Thus, appropriate assessment and treatment for sleep disorders in patients with ADHD is essential.

Objectives: This study was performed to analyse single dose toxicity of pure melittin(Sweet Bee Venom-Sweet BV) extracted from the bee venom by utilizing protein isolation method of gel filtration. Methods: All experiments were conducted at Biotoxtech, a non-clinical studies authorized institution, under the regulations of Good Laboratory Practice (GLP). Six weeks old female Sprague-Dawley rats were chosen for the pilot study and determined 30㎎/㎏ which is 4285 times higher than the clinical application dosage as the high dosage, followed by 15 and 7.5㎎/㎏ as mid and lose dosage, respectively. Equal amount of excipient to the Sweet BV experiment groups was administered as the control group. Results: 1. No mortality was witnessed in all of the experiment groups. 2. Hyperemia and movement disorder were observed around the area of administration in all groups, and higher occurrence in the higher dosage groups. Hyperemia and movement disorder diminished with elapsed time. 3. For the weight measurement, male groups showed larger reduction in weight in accordance with higher dosage. Female groups didn't s how significant changes. 4. To verify abnormalities of organs and tissues, cerebellum, cerebrum, liver, lung, kidney, and spinal nerves were removed and conducted histological observation with H-E staining. No abnormalities were detected in any of organs and tissues. 5. One female rat in the 30㎎/㎏ group had amputated toe near the administered area and histopathological finding was hemorrhage with inflammation. This is presumed as a secondary infection after the administration of Sweet BV. Conclusion: Above findings suggest Sweet BV is relatively s safe treatment medium. Further studies on the subject should be conducted to yield more concrete evidences.

The public health service center and its branch are, as one of public institution, responsible for providing non-profitable medical service to local residents, which can't be addressed by private medical institutes. In addition, as a planning coordinator, they need to manage local medical resources effectively to make sure local residents can be offered good-quality health service fairly and impartially. The purpose of this study was to highlight the importance of physical therapy in public health service center's successful role performance, one of treatment to which local residents had a direct access. For attaining the purpose, an investigation was made into the actual facilities of public health service center and its branches in North Cholla province, the extent of use of physicaltherapy room, and the general characteristics of physical therapists. And literatures concerned were referred to. As a result, the dominant opinion was that the current physicaltherapy room shoulder be more reinforced(38.9%) or that it should he kept as it was(46.5%). Besides, the physical therapists investigated still were serving in a poor working condition. To elevate the quality and quantity of medical service, the current way to employ expert personnels temporarily or not to guarantee the position of physiotherapists should be removed immediately. Instead, physicaltherapists should be employed as regular public official. As, in home-visit project, physiotherapist are expected to play a bigger role in rehabilitation care or the management of patients with chronic disease, the physicaltherapy room should be increased and more physicaltherapists should be provided to health service institutions.

Objectives: The objective of the study was to resolve various elements of conflict by presenting the results of the study and to help build an enhanced oriental medical service system. Methods: The researcher collected data from 12/15/2006 to 1/31/2007. A total of 1000 questionnaires were sent out to oriental medical doctors working at oriental medical facilities and the 15% (150 questionnaires) of them that were returned completed were analyzed. Results: 1. As to the proper proportion of oriental medical doctors to western medical doctors, they said it should be less than 20%. About separating the task of prescribing oriental medicine (herb) from oriental medical treatment, 80.7% of them were against it. 98.7% said oriental medical doctors needed the control of medical technicians. 2. 72.3% said they had no intention of taking the U.S. NCCAOM board to practice oriental medicine overseas. A majority (57.7%) were in favor of unifying oriental medical license with western medical license. 3. Oriental medical doctors had greater job satisfaction [than all oriental medical doctors number]. If they were to choose another occupation than oriental medicine they would consider becoming a research fellow above all other occupations. If they were to reenter college, they said they would probably choose oriental medical school. However, the choice of reentering oriental medical school was lower than that of western medical school. Conclusion: This study has also statistically determined the current issues that may pose conflicting views on the part of the respondents. A periodic study such as this one will hopefully aid in establishing policies for oriental medicine.
